Fifth grade teacher Courtney Elizabeth Warner has been a beauty vlogger since 2014 and has amassed hundreds of thousands of followers.

Most famous for online makeup tutorials, she shared a very different video with her fans last May when she announced that she had been diagnosed with a brain tumour.

In the video, she explains that she had just come home from visiting her sister in Chicago when she began to feel unwell.

She heard a ‘very weird’ sound in her ear and all of a sudden couldn’t form words or type or create sentences and immediately began to ‘freak out’.

After finding out that it could grow and eventually become cancerous she was told that surgery was her best option.

Fast forward six weeks and on June 28th, Courtney posted a video of herself in the operating room, having surgery.

Despite having mixed feelings about the footage, she explained that she thought it was really ‘interesting’ to show people what her surgical procedure had been like – from her perspective.

The tumour was located in the part of the brain that controls speech, so Courtney was awake and talking through the surgery.

If you’re squeamish, don’t worry. There’s no blood or brain shots in the video (the operating room footage begins at 4.52) but at one point, she does have a minor seizure that may be a little upsetting.

Thankfully, everything went well and, although Courtney still experiences occasional difficulty with her words, she is thrilled with how well her recovery is going.
